OF BAY CITY, MICHIGAN.

MACHINE FOR FERRULING SHADE-ROLLERS,

SPECIFICATION forming part of Letters Patent No. 759,360, dated May 10, 1904.

. Application filed October 29, 1903.

To all whom, it may concern:

Be it known that I, CLAUDE FLAGLER, acitizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Machines for Ferruling Shade- Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such. as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a machine for attaching metal ferrules to the ends of shade-rollers and for depressing the edge of the ferrule where it overlaps the roller, so that the ferrule edge will not project above the surface of the roller.

The improvements consist in the parts, their combination 'and operation, and the equivalents thereof, as will be fully set forth in the specification and claims of this application.

The mechanisms comprising the machine are arranged to perform the following functions: First, to reduce the diameter of one end of the shade-roller by compressing the fibers of the roller to such an extent that a ferrule having its outside diameter equal to the diameter of the roller will fit over the compressed end, then to force the end of the roller into the ferrule, then to compress the circumference of the ferrule at its inner end, so as to crimp the ferrule end into the roller, and thus lock the ferrule against coming off the roller. 7

With these objects in view, together with certain others that will appear later in this specification, the machine consists in the combination of devices illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the ferrulingmachine. Fig. 2 is a top plan View of the same. Fig. 3 shows in perspective the end of a roller and the ferrule which is to be fitted to it by the machine. Fig. 4 shows the end of the roller with the ferrule attached. Figs. 5, 6, and 7 are respectively part sectional views illustrating the various steps by which the ferrule is secured to the roller.

Fig. 20 is a side view of the friction-brake for limiting the movement of the conveyer. Fig. 21 is a front view of the same. Fig. 22 is a vertical section taken on the line y 901? Fig. 2, showing in side elevation the conveyer for feedingthe rollers into and ejecting them from the machine.

The object of the machine, as has been indicated, is to automatically feed a roller and a ferrule into proper alinement in the machine, then to force'the end of the roller through an opening of slightly-smaller diameter than the roller and into the ferrule, then to' further compress the end of the ferrule preferably clear around its circumference, and then to discharge the ferruled roller from the Having these objects in mind, the general operation of the machine can be better understood by reference to Figs. 3, 4, 5,

6, and 7 of the drawings, in which 1 is the end of the roller to be ferruled, and 2 is the pawl-plate to be held against the end of the roller by the ferrule, and 3 is the ferrule, which is preferably a thin cylindrical shell that may be provided, if desired,with an annular flange 3 at one end to hold the pawl-plate 2 in place. In order to make the completed roller of the same diameter from end to end, the outside diameter of the ferrule is preferably made the same as the outside diameter of the roller.

Hence the inside diameter of the ferrule will be somewhat less than the diameter of the roller, and the latter must be reduced before the ferrule can be slipped over it. I reduce the end of the roller by forcing it through an opening 4, formed in a pair of dies 4, the

opening being of the same diameter as the inside diameter of the ferrule 3. The edges of the dies 4 are preferably rounded or tapered, so that the fibers of the roller will be compressed and not torn when the end of the roller is forced through the opening. The ferrule-plunger 5 holds the ferrule 3 in place just back of the opening 4, and when the end of the roller 1 passes through the opening it immediately enters the ferrule 3. In practice this is done very quickly, almost with the rapidity of a blow. The end of the roller at this stage of the operation is in the position indicated in Fig. 5. The next movement is to push the ferrule-plunger 5 toward the dies 4 a short distance, thus forcing the end of the ferrule 3 through the opening 4, compressing the metal of the ferrule and crimping its edges into the fibers of the roller to form a circumferential depressed bead that effectually locks the ferrule. in place. This movement is indicated in Fig. 6. After the edge of the roller has been crimped the jaws 4 of the die separate, as shown in Fig. 7. The ferrule-plunger 5 advances still farther and ejects the roller and ferrule from the opening 4*.

Having described the general mode of operation, I will now point out the mechanisms by which these operations are timed and effected in proper order, but with extreme rapidity.

The working parts of the mechanism are mounted on any suitable frame, as 6. In Figs. 1 and 2 the mechanism that accomplishes the ferruling is shown at the left-hand side, and the mechanism for automatically feeding the rollers into and discharging them from the matehine is shown at the middle and right-hand si e.

I will first describe the device for feeding the rollers into the machine. This device is illustrated in Figs. 1 and 2. 7 7 are sprocketchains mounted on suitable wheels 7 and carr yin g curved bracket 7 into which the rollers are fed either by hand or from a suitable hopper. the bed of the machine, stopping it in direct alinement with the die-opening 4 long enough for the ferruling operation to be performed. The chain then advances to feed the next roller into position. Intermittent step-by-step movement is imparted to the chain 7 by the device illustrated in Figs. 2, 17, and 18, where 8 is the driving-shaft. to which the sprockets 7 are fixed, and 8 is a ratchet-wheel mounted thereon. The ratchet-wheel is operated by a pawl 9, mounted on a bell-crank lever 10, the free end of which engages the end of the arm 11, pivotally mounted on the frame of the ma- The chains 7 carry each roller across chine by means of a pin or pivot 11* and having an up-and-down movement. The other end of the arm 11 engages the outer end of the bell-crank lever 12, the opposite end of which contacts with a moving part of the mechanism as, for instance, the pin or wiper 13 that projects from the face of the disk 13, which operates the ferrule-plunger 5. The spring 14 is attached to the bell-crank lever 12 to restore it to its original position after being displaced by the wiper 13. As the disk 13 revolves the wiper 13 operates through the levers to move the ratchet 8 one tooth forward, thus operating the chain 7 to bring the next roller into alinement with the die-opening 4. In order to prevent the chain 7 from moving too far, a friction-wheel 15 is fixed to the shaft 8, and a friction-band 15 of any suitable form, secured to the frame 6, is passed around the wheel 15 and provided with the clampingscrew 15", whereby its frictional effect may be regulated. When the roller comes into alinement with the opening 4, its end is immediately forced into the opening, as previously described. This movement is accomplished by means of the driving-plunger 16. (Shown in Figs. 1 and 2 and further detailed in Fig. 9.) The plunger is preferably mounted on a spindle 16, slidably mounted in suitable bearing 16, and I prefer to employ the mechanism shown in Fig. 19 to give it the necessary forward driving movement and recoil. An upright lever 17,pivotally mounted at its lower end to the frame 6, is pivotally connected at its upper end to the spindle 16". A link 17 connects this lever with a similarlymounted upright lever 18, the free end of which is adapted to be contacted by any suitably-timed moving part of the machine. The wiper 18 is well adapted to this purpose, and I therefore prefer to mount the lever 18 so as to engage this wiper at the proper time. By placing the lever 18 on that side of the center of the disk 13 opposite the lever 12 the wiper 18 will first operate the lever 12, moving the roller into alinement with the dieopening 4, and then will engage the end of the lever 18 and operate the plunger 16 to force the end of the roller into the opening. The plunger is restored to its original position by the coiled spring 18 or any suitable device.

Having described the means by which the roller is first brought into alinement with the die-opening and then forced a short distance into the opening, I will now describe the means by which the ferrule is brought into alinement with the end of the roller and held while the roller is forced into it, and then the end of the ferrule is crimped, after which the opening 4 is increased in size and the roller is ejected therefrom; The devices by which these results are attained are illustrated in Figs. 1, 2, and 8 to 16, inclusive, where 19 is the driving-shaft mounted in suitable bearings in the frame of the machine, and 19 is a gear-wheel revolubly mounted on the shaft, but adapted to be locked thereto when desired. The wheel 19 may be driven by any suitable driving-pinion. The disk 13 is keyed to the shaft and carries a suitably shaped camgroove 13, which engages a projection 20 slidably mounted in horizontal guides 20? and adapted to operate the ferrule-plunger 5 toward and from the dies 4: in the manner previously described. 'By properly shaping the cam-groove l3 .the movement imparted to the plunger 5 is such that it first draws back to permit the insertion of a ferrule in the space 5 between its end and the dies 4:. The ferrulemay be inserted by dropping from a suitable chute into which a number of ferrules may be fed at a time. The chute is omitted from the drawings for the sake of clearness.

cept at the instant when the crimping is ac' complished. They are closed when the end of the roller is forced into the opening 4: and

closed when the plunger 5 forces the ferrule' back to crimp its edge; but they then suddenly open to permit the uncompressed body of the ferrule to be discharged through them. To accomplish this movement, I mount the dies t on suitable guides 6 and connect them by means of suitable toggle -links 21 to slidable bars 21, which carry at their rear ends projections 21, adapted to engage suitable camgrooves 22, provided in the disks 22, that are fixed to revolve with the drivingshaft 19. The cam-grooves 22 are properly timed to release the die-jaws 4 at the instant the crimping of the ferrule edge is completed.

In order to start and stop the machine at will, I prefer to provide a suitable clutch by which to interlock the hub of the gear-wheel 19 and the disk 22. This clutch and the means by which it is actuated may be of any of the various well known constructions.

While I have shown and described preferred forms of mechanisms which I have found in practice to be satisfactory to attain the desired results, yet I do not desire to confine myself to the particular forms herein described, as other devices may be employed to accomplish the same results in substantially the same manner without departing from the spirit of my invention.
